To construct a confidence interval for the difference between two population means mu 1 minus mu 2, use the formula shown below when both population standard deviations are known, and either both populations are normally distributed or both n 1 greater than or equals 30 and n 2 greater than or equals 30. Also, the samples must be randomly selected and independent. left parenthesis x overbar 1 minus x overbar 2 right parenthesis minus z Subscript c Baseline StartRoot StartFraction...
